4 Claims.

This invention relates to pocket spray devices, and more particularly relates to pocket devices which may, with slight adjustment of parts, operate as sprays or atomizers.

The invention is directed to a particular construction of parts which permit; easy and simple manufacture, and includes the feature `that no leakage can occur in the device when it is not in operating position.

Pocket sprays and atomizels have previously been proposed, but for the'most part they possess the diiiiculty that leakage is bound to occur, as they are carried by the individual user and for this reason they have been found to lack practical application. Many such devices havethe further disadvantage that no provision is made to supply air to the liquid container to replace removed liquid, so that if such devices operate at all their operation is uncertain and irregular. Furthermore such devices are either sprays or atomizers and one cannot be modified to perform the functions of the other, which is a disadvantage when various types of liquids are to bev provided for.

It is an object of this invention to provide ay pocket spray device which may, by adjustment of' very simple parts, be made into an atomizer or a spray, as the manufacturer may desire, thus providing spraying devices for liquids of a wide range of specic gravity, and which, in either case, will be a complete leak proof combination of parts from which liquid can only be obtained as is desired by the user.

It is an object of the invention to provide a spray device in which ample provision is made to replace removed liquid in the liquid containerv with air, without causing any undesired leakage 1n the device, thus insuring continuous smooth operation.

A further object of the invention is to produce Such a spray device with very small over-all dimensions, and which may be carried in a ladys pocketbook ora gentlemans pocket.

Further objects and Aadvantages will appear from the following description and the appended drawing in which Figure 1 is a vertical section of device embodying the construction of the invention;

Figure 2' is a section similar to Fig. l, showing a sprayer construction having a modified contai'ner;

Figure 3 is a section similar to Fig. 1, showing ing the parts adjusted for atomizing;

Figure 4 is' a detailed showing oi` the spray construction of Fig. l; and

terial or may be of opaque material such as plastic or metal. The bottle I is provided with a threaded metal collar i I about its neck which permits it to be easily secured to the other part,Q of the construction. Located Within the liquic container I0 is the cylindrical air chamber I2 which contains a piston I3 provided with port I5 and secured to a plunger I4, the spring I5 tending to push the piston and plunger upwardly when thede-vice is operated. The port IB may take any convenient form and is intended only to provide for introduction of air into the space below the pistononv its up stroke, thus eliminating the possibili-ty of liquid beingdrawn. into the cylinder.

The top portion of the device is provided with a collar member I' I having an interiorly threaded portion I8 which' cooperates with the collar il of the bottle Ill. Member Il extends inwardly at 22 and hast-the downward step I9 and terminates on its inner side with the threaded cylindrical portionl The gasket2l insures that no leakage will. occur at thetop o f the bottle I U.

lThe inverted cup-shaped member is provided with threads 2B on its outer side which cooperate with the threaded portion 20 of the collar I'I. A shoulder 2l is provided on the member 25 directly below the threads 20 and limits the downward movement of the collar member Il. The cup-shaped member 25 has a top horizontal platform 28 in whichv the air vent 29 is provided. The platform-28 also has the threaded hole 30 which in thisembodiment contains the plug 3 I. On one side of the member 25 is provided the threaded hole 32.

The tube 34 from air chamber I2 has descending portion 39, hole 35 near the bottom or the liquid container, and ascending portion 36 which turns outwardly at 31 into spraying zone 38 which may take any convenient form which will break member 25 and will lit into the step portion I9, the gasket 42 fitting snugly over the platform 28 so that the cap forms an eective seal against leakage. The gasket 23 may also be provided in the step I9 further to seal the cap 40.

To operate the device the cap 40 is unscrewed and the piston is operated up and down forcing air under compression through tube 34 which air displaces liquid at 35. The mixture of air and liquid is vbrokengup at 38 and a ne spray is ejected throughthe'hole 32.

In some cases it is particularly desirable, due to the nature of the liquid material to be carried, to use glass or other inert material for the liquid container. In such cases it may also be desirable to have a more durable outside container of metal or the like. In Fig. 2 such a construction is shown, using however the samel parts to mount the liquid container and outside shell. Thus the collar member I1, cup-shaped member'25, and cap 40 are precisely the same as in the construction of Fig-1. The interior liquid container D of glass or other convenient inert material has extericrly threaded neck 5I which is screwed into the interiorly threaded portion of the inverted cup-shaped member 25. The gasket 52 is provided to prevent leakage from the top of the interior bottle 50.`

In Figure 3 a constructionv is shown which adapts the parts used-in Figures 1 and 2 for use asan atomizer. The outside container may be as in Figs. 1 or 2, or may, as shown, be of metalor plastic, and may, if desired, have the bottom cap 60 to facilitate reiilling. In this construction a tube 64, downwardly extending from the air chamber 65, is provided with no hole as described in the iirst two embodiments. A second tube 66 Vascends from below the liquid level vto slightly above the platformv 28. Tube 64 terminates above platform 28 and is formed to point over the top of 'the tube 66 so that emission of air at high velocityfrom the tube 64 will cause liquid to be drawn up the tube 66 and to be atomized in the direction which the tube 64 is pointing. It is seen that in this embodiment the hole 32 is plugged. The tube 66 preferably terminates at its lower end in substantially horizontal portion 61 and upwardly turned portion 68 which'will operate to insure thatno leakage occurs through this tube.l The tube 64 is provided with the air vent 69 which supplies air to replace the liquid removed through tube 66, thus insuring regular and steady flow of atomized liquid. Y y

Comparing now the'three types of spray devices shown in Figs. 1, 2, and 3, lt will be seen that many parts may be used commonly for all three types and the expense of manufacturing will be considerably below that required to manufacture an ordinary spray and an ordinary atomizer. The outside container may, as stated, be interchangeably used either as a guard for a bottle or as the liquid container itself.v The piston and vplungerl construction obviously may be used interchangeably, as may the collar I1, the cup-shaped member and the cap 40. It is further possible toadjust an atomizer into a spray or vice versa should the user so desire. This may be accomplished inthe case of a spray by re wplacing the tube 34which has the hole 35 with a tube. such as 64 having no hole, and by remov- Aingjtheplug 3! `from the hole 36, placing it in the Ahole 32, and providing a further hole 69 adjacent the hole 3l) for tube 64.

In Figure 5 is shown a slightly modiecl construction of atomizer including the liquid container 15 which, it will be noted, is merely a tube having a slightly undercut portion at its lower end to accommodate the bottom cap 1I and having an interiorly threaded zone 12 at its top. The bottom cap may also be formed integrally with the tube 1Q. An inverted cup 13 is utilized in this construction to close the top of the liquid container, said closure member having a threaded cylindrical portion 15 which engages the thread 12, an annular shoulder 15 preferably having gasket 16, a cylindrical portion of less diameter 11, and a top platform 18. Cap member 'I9 is secured to the plunger and has an exteriorly threaded portion which cooperates with the threaded portion 12, the lower parts of the cap 'I9 fitting into the groove formed by threaded portion 12, the annular platform 'l5 and the cylindrical portion 11, and are sealed against leakage by the gasket 16. The atomizer portion of this construction is similar to that described in connection with Fig, 3. Considerable economies of manufacture may be effected in the iashioning and assembling of these simple parts, particularly since the tube and cap member 13 are so easily constructed.

While I have illustrated and described in detail certain preferred forms of my invention, it is to be understood that changes may be made therein and the invention embodied in other structures. I do not, therefore, desire to limit myself to the specic constructions illustrated, but intend to cover my invention broadly in whatever form its principle may be utilized.
